碎裂电位是心房颤动发生和持续的因和果,其机制与心脏自主神经密切相关。心脏内源性和外源性自主神经共同作用,增加心房的早期后除极和钙瞬变,导致碎裂电位和心房颤动发生。因此碎裂电位与自主神经节丛或脂肪垫分布一致。针对自主神经节丛消融,可以减少或消除碎裂电位。 Fragmentation potential is the cause and effect of atrial fibrillation and sustained, its mechanism and cardiac autonomic nervous closely. Cardiac endogenous and exogenous autonomic interaction, increase the atrial early post-depolarization and calcium transients, leading to fragmentation potential and atrial fibrillation. Therefore, fragmentation potential and autonomic ganglion plexus or fat pad distribution. For autonomic ganglia ablation, can reduce or eliminate the fragmentation potential.
